Rosen MD and Michael Hausman MD Abstract Digital imaging has provided orthopaedic surgeons with new powerful tools that offer a multitude of applications. Already integral to several common medical devices digital images can be used for case documentation and presentation as well as for diagnostic and surgical patient care information. Educational presentation has been transformed by the use of computers and digital projectors. Understanding the basic foundations of digital imaging technology is important for effectively creating digital images videos and presentations. J Am Acad Orthop Surg 2003 11 373-379 Before the advent of computers information could be stored only on a physical object such as a phonograph record audiotape or photographic lm. Digital technology allows data whether printed information sounds photographs or video to be stored as a binary number rendered in a string of 0s and 1s. This independence from physical objects is the principal advantage of digital technologies. Because the information is stored numerically it can be transmitted in many forms. The difficulty in digital technologies lies in converting physical analog entities into and out of numeric values. Advances in the speed memory and video displays of modern computers continue to drive these digital principles into every facet of life. Digital imaging technologies are already incorporated into the medical record systems and radiology departments of many hospitals. However as with any evolving technology rival and conflicting standards may hinder the seamless transfer and use of information. Furthermore there is confusion about the proper format and standards in which to store digital images and video. Pixels Each digital image is divided into squares called pixels. A pixel or picture element is the smallest unit of visual information that can be used to build an image. Pixels are the .
